(743g) Advanced Electrokinetic Desalination for Brackish Water: Water and Energy Nexus

This work explores the state-of-the-art electrokinetic processes for brackish water desalination, as well as identifying emerging technologies and potential advances via materials science, process engineering, and system integration. We focus on two major types of electrokinetic processes: electrodialysis/electrodeionization and capacitive deionization. We discuss the balance between energy efficiency and throughput in the context of large-scale deployment of a desalination plant to address the associated challenges in water and energy nexus. Thermoelectric power plants traditionally have required huge volumes of water to condense steam from the turbine exhaust. The complex interdependency between water and energy poses new challenges for policy makers to achieve a secure and sustainable supply of water and energy in the future. In order to facilitate the use of impaired water in cooling systems, we suggest the key technical issues and available water technologies for brackish water desalination.
